FEED-MACHINE ATTACHMENT FOR PRlNTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 480,448, dated August9, 1892.

Application filed November 24, 1891. Serial No. 412,990. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS A. BRIGGS, of Arlington, in the county ofMiddlesex and State of Massachusetts, have invented new and usefulImprovements in Feed-Machine Attachments to Printing-Machines, of whichthe following, taken in connection with the accompanying drawings, is afull, clear, and exact description.

This invention relates to the attachment of the supporting-frame of apaper-feeding machine to the frame of a printing-machine; and the objectof this invention is to adapt the said paper-feeding machine to bereadily at tached to the frame of the printing-press and also readilydetached therefrom when desired to feed the paper by hand to theprinting-machine; and to that end the invention consists in the novelconstruction and combination of parts hereinafter fully described, andset forth in the claims.

In the annexed drawings, Figures 1 and 2 show opposite sides of theframe of the paper-feeding machine and its connection with theprinting-machine. Fig. 3 is an end view of the same. Fig. 4isahorizontal transverse section on line a; 00, Fig. 1. Figs. 5 and 6are vertical transverse sections, respectively, on lines y. y and z 2',Fig. 4. Fig. 7 is a vertical transverse section of the socket whichcontains the frame-supporting roller, said section being taken in aplane at right angles to the axis of the roller; and Fig.8 is ahorizontal transverse section on line 0 0 in Fig. 5.

Similar letters of reference indicate corresponding parts.

A represents the feeding end of the main frame of a printing-machine,and T denotes the usual feed-table, over which to pass the sheets ofpaper to the printing-machine. To the feeding end of the frame I attachremovably a supplemental frame B, consisting, mainly, of four posts Pand P, two on each side of the frame, and tied to each other by a broadcross-bar B at the bottom, heads B B" respectively at opposite sides ofthe frame B and provided with sockets s s for the reception of the upperends of the posts, and a cross-bar B, tying said heads to each other, asshown in Fig. 3 of the drawings. I prefer to hinge saidsupplemental'frame to one side of the feed end of the frame Aby firmlysecuring to the latter the brackets C C, which are formed with verticalsleeves e e, and through these sleeves passes the post of thesupplemental frame, said post constituting the pivot on which thesupplemental frame can be swung to or from the feed end of theprinting-machine, as may be desired. The opposite side of thesupplemental frame is detachably connected to the main frame A by meansof a suitable strap or book 71, as shown in Fig. 2 of the drawings.

Under the supplemental frame is a baseplate D, which is formed with asocket f, in which is stepped the post P, by which the supplementalframe is hinged to the main frame. This base-plate is also formed with asegmental track If, concentric to the socket f and extending underneaththe frame B, preferably at the center of the width thereof and rearwardtherefrom, as best seen in Fig. 4 of the drawings. Upon this track ismounted a roller 0, which supports the supplemental frame B at thecenter of its width, and is adjustably connected thereto by means of avertical yoke 19, to which the roller is pivoted and which is seated invertical grooves a a in opposite sides of a socket a, formed in theunder side of the cross-bar B, as shown 1n Figs. 5, 6, and 7 of thedrawings. Through the top of the cross-bar B, central over the yoke 12,is a screw threaded eye, through which passes a set-screw d, which bearswith its lower end on top of the yoke and thereby supports thesupplemental frame on the roller 0. By turning the said set-screw theframe B can be raised or lowered and properly adjusted to its uprightposition.

F represents the table upon which is piled the sheets of paper to be fedto the printingmachine. This table is mounted on brackets F, which areadjustably connected to the rear posts P P of the supplemental frame B,so as to allow said table to be raised or lowered, as may be required.Said adjustable connection may be made in any suitable manner, and is inthis case shown in the same form as represented in another applicationfor Letters Patent of the United States of even date herewith andbearing the Serial No. 412,989, and consists of two horizontal IOOshafts 1 1, extending across the frame B and ournaled in the brackets FF in front and rear of the posts P P, which latter are provided wlthcogs forming two vertical racks on each post. To each of the said shaftsare secured two pinions 2 2, which engage the racks on the front andrear of the posts. At the outer side of one of said posts is a vertlcalworm-shaft 3, journaled to the frame B, and 1n ears 4 4 on the bracket Fand in front and rear of the worm-shaft are wormwheels 5 5, fixed to theshafts 1 1. To the upper end of the worm-shaft 3 is attached annter-pinion 6, meshing'with a similar pin- 1011 7, pivoted to the sideof the frame B. The latter pinion may be rotated either by a hand-crank,as indicated by dotted lines in Fig. 1 of the drawings, or receivemotion from the paper-feeding mechanism, as shown in my otherapplication for United States patent hereinbefore referred to. Therotatron of the worm-shaftimparts rotary motion to the shafts 1 1, whichby means of the engagement of their pinions 2 2 with the vertlcal rackson the posts P P raise or lower the table, according to the direction inwhich the worm-shaft is rotated.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is

1. On a printing-machine, the combination,

a with the main frame, of a supplemental frame lunged to one side of thefeeding end of said main frame, a paper-supporting table carried on saidsupplemental frame, a segmental track under the latter frame andconcentric to the hinge thereof, and a roller connected to thesupplemental frame and traversing on the aforesaid track, as set forthand shown.

2. On a printing-machine, the combination, with the main frame A, of thesupplemental frame B, hinged to one side of the feeding end of the mainframe and formed with a cross-bar B and with the socket a, in the underside of said cross-bar and having vertical grooves a a in opposite sidesof said socket, the yoke b, seated movable vertically in said grooves,the roller 0, pivoted to said yoke, and the set-screw d, passing throughthe top of the cross-bar and bearing on top of the yoke, substantiallyas described and shown.

3. The combination, with the main frame A, of the brackets C 0, attachedto one side of the feeding end of said frame and provided with thevertical sleeves e e, the supplemental frame B, provided with sleeves ee, the post P, passing through the aforesaid sleeves and hinging thesupplemental frame to the main frame, the base-plate D, provided withthe socket f, having stepped therein the post P and formed with thetrack t concentric to said socket, the roller 0, mounted on said trackand supporting the central portion of the supplemental frame, and thetable F, connected to the post P adj ustably in its elevation,substantially as described and shown.

In testimony whereof I have hereunto signed my name this 16th day ofNovember, 1891.
